I have a 92 dodge stealth sohc when i got it it had fuel issues i replaced fuel filter, spark plugs, distributer cap and roter. Seemed to run fine after that but now it overheats and problems start over. I replaced termastat, flushed rad and checked water pump. Could it be a fuel pump relay? My understanding that the relay is dual function for fuel pump and ecu if someone could help would be nice

I owned a 91 model--glad you have the sohc as the dohc has real problems.

some general thoughts:

The relay is possible but does the electric fan come on? If it does not after 10 minutes it will overheat.

Saw two where water pump caused same issue.

Check for possible head gasket leaking(compression tested?)

Another valuable resource I have used is the Socal 3S club located in the LA area of California---they have a online forum with areas for problems and solutions---free to join and they have several segments for parts and problems and general back and forth.

Again my experience here is based on owning both a SOHC and a Twin Turbo made in 91-----not like working on a ford...........

Let me know if I can help in any way----you are more likely to get good help from one of the many forums dedicated to these cars than here.
